Writing jpeg images to movie - .avi size and timestamp on image

Hi all,

The code below creates a .avi movie from a collection of jpeg files. The code works fine but I want to do two things:

(i)Reduce the size of the resulting video - quality of video is not that important

(ii)Add a visual timestamp to images (video)

Any suggestions on how best to go about this?

Thanks, Dom

if true
  % Create a VideoWriter object, in order to write video data to an .avi file using a jpeg compression.
  VideoFile = ['op1_mx',num2str(mx),'_',files(f).name];
  writerObj = VideoWriter(VideoFile);
  fps = 10; % Define the video frames per second speed (fps)
  writerObj.FrameRate = fps;
  open(writerObj); % Open file for writing video data
  % Running over all the files, converting them to movie frames using im2frame and writing the video data to file using writeVideo
  for t = 1:length(jpegFilesS)
      disp(t);
      Frame = imread(strcat(ImagesFolder,'/',jpegFilesS(t).name));
      writeVideo(writerObj,im2frame(Frame));
  end
  % Close the file after writing the video data 
  close(writerObj);
end
